Unit 1 at the Belarusian NPP was put into scheduled preventive maintenance and partial refuelling on 27 April. As part of the planned work, the reactor plant equipment will be repaired, including steam generators, pressure compensator, main circulation pumps and a turbogenerator, as well as metal inspection and diagnostics of welded joints of the reactor equipment and pipelines of systems important for the safety of the power unit. Unit 1, a VVER-1200 supplied by Rosatom, began commercial operation in June 2021 since when it has generated 9.3 TWh.

China National Nuclear Corporation (CNNC) said on 26 April that unit 3 at the Qinshan NPP in Zhejiang province (a pressurised heavy water reactor) has begun the world’s first production of carbon-14 radioactive isotopes using a commercial reactor. The plant expects to start supplying carbon-14 radioactive isotopes to the market in 2024 and that its production capacity can fully meet domestic demand.

Unit 6 at China’s Hongyanhe in Liaoning province achieved first criticality on 21 April, China General Nuclear (CGN) announced. Hongyanhe 6 is the second of two ACPR-1000 reactors built as Phase II of the plant and is scheduled to begin commercial operation later in 2022. CGN said this “marks the official entry of the unit into the operating state with power” in preparation for the subsequent ramp-up, grid connection and commercial operation.

The Japan Atomic Energy Agency (JAEA) and Mitsubishi Heavy Industries (MHI) said on 22 April that they had been commissioned by the Agency for Natural Resources and Energy (ANRE) of the Ministry of Economy, Trade and Industry to develop hydrogen production. The hydrogen mass production technology demonstration project will begin this year using the High Temperature Engineering Test Reactor High Temperature Gas Reactor (HTTR). A hydrogen production facility will be connected to the HTTR owned by JAEA to develop hydrogen production technology utilising the reactor’s high temperature heat.

Unit 3 at Finland’s Olkiluoto NPP was shut down on 26 April as part of a test programme, plant owner-operator Teollisuuden Voima Oyj (TVO) said. However, the boron pumps started unexpectedly. TVO said the plant “is in a safe state” and “the reason for starting the boron pumps regulating the chain reaction is being determined”. A subsequent announcement said the boron pumps (safety system) had started unexpectedly “due to an incorrectly triggered signal from the automation system”. The fault has been rectified and the plant's test operation programme is continuing “in accordance with the production forecast”.

Finland’s Posiva Oy has launched a project for modelling the groundwater chemistry in the bedrock of the site for the final disposal of used nuclear fuel far into the future using one of the most efficient computers in the world. Posiva, which is responsible for the final disposal of used nuclear fuel, is jointly owned by Finnish nuclear utilities Fortum and Teollisuuden Voima Oyj. “This is probably the most demanding modelling of groundwater chemistry to date, anywhere in the world. The goal of the project is to verify the balancing of long-term safety with economic sustainability. This will open the way to industrial final disposal far into the future,” Posiva noted.

Purdue said in a statement that the move may be “unprecedented for a college campus”, but an SMR could meet current and future needs for the university’s West Lafayette campus and provide excess power to the state’s electric grid.
According to the statement, Purdue is powered today by the onsite combined heat and power Wade Utility Plant, which has three gas-fired and one coal-fired boilers.

The repository is the first consolidated interim storage facility for Russian VVER reactor fuel. Construction began in 2017, although initial contracts with main contractor US-based Holtec International were signed in 2005.
Energoatom said the CSFSF was completed in 2020 and entered test operation mode. The official operating permit was expected on 9 March 2022, but the recent occupation by Russian forces of the Chernobyl nuclear station and exclusion zone delayed the plans.
